OpenClaw social media posting: connect PostWire's MCP server with one command

Set it up and post, step by step

1. Register the server on your gateway

   On the machine where OpenClaw runs, save PostWire as a remote MCP server with OAuth. This is OpenClaw's own form for a remote HTTP server:

   openclaw mcp add postwire \
     --url https://postwire.io/api/mcp \
     --transport streamable-http \
     --auth oauth

2. Sign in with your email

   Run openclaw mcp login postwire. OpenClaw prints an authorization URL; open it, type your email and the 6-digit code PostWire sends you, and approve. That also creates a free PostWire account if you have none: no password and no card. OpenClaw keeps the token and refreshes it.

3. Check that the tools are there

   Run openclaw mcp doctor postwire --probe. The probe opens a real connection, so it shows the server answering and its tools: 21 of them, among them generate_posts, post_to_social, schedule_post, list_scheduled_posts and get_post_status.

4. Connect your social accounts

   Message OpenClaw: "connect my LinkedIn and my Bluesky". create_connect_link returns a one-hour link; open it and sign in to each network on its own page (Bluesky, Mastodon, Telegram and Discord take an app password, a token or a webhook there). OpenClaw never sees those passwords: it holds a PostWire token, and PostWire holds the accounts.

5. Let PostWire write each network's post

   "Write this week's product update for LinkedIn, Bluesky and Telegram." generate_posts returns one draft per network and publishes nothing: a longer first-person post for LinkedIn, a conversational one of up to 300 characters for Bluesky, a clear and direct message for Telegram.

6. Publish, or schedule it

   After you approve in the chat, OpenClaw calls post_to_social, or schedule_post with a run_at time (or "next_slot" for your next free queue slot):

   {
     "name": "schedule_post",
     "arguments": {
       "platforms": ["linkedin", "bluesky"],
       "per_platform": {
         "linkedin": { "text": "We shipped CSV import this week. Here is what took us three tries to get right…" },
         "bluesky": { "text": "csv import is live. it took us three tries, ask me which one hurt most" }
       },
       "run_at": "2026-10-20T09:00:00-05:00"
     }
   }

7. Ask what is queued and what went out

   "What's scheduled this week?" calls list_scheduled_posts; cancel_scheduled_post removes one before it goes out, and get_post_status returns each network's result with the link to the live post.

The commands are OpenClaw's own, from its MCP documentation (read Oct 13, 2026); if your version differs, openclaw mcp --help is the reference. Prefer to set it up by hand first? Open the dashboard, connect the account under Accounts and copy your key under API & MCP.
